Just hours after Gov. Chris Christie announced he’s running or re-election, a new poll shows a strong majority of New Jersey voters are behind him.

The poll also shows Christie dominating all of his potential Democratic opponents. Newark Mayor Cory Booker fares best against Christie in the poll, but the governor still leads him 53 percent to 34 percent. Next closest is state Sen. Richard Codey (D-Essex), who Christie leads 56 percent to 31 percent.

None of the other Democrats mentioned in the poll — State Sen. Barbara Buono (D-Middlesex); Assembly Majority Leader Lou Greenwald (D-Camden); and former Democratic State Chairman Tom Byrne, whose father is former Gov. Brendan Byrne — break 22 percent.

Just two months ago, 44 percent of voters said they supported Christie’s re-election while 47 percent opposed it.

“Before superstorm Sandy, things looked much different for Christie, as Democrats seemed positioned for a serious challenge next year,” said poll director David Redlawsk. “Voters were evenly split over the governor’s re-election, and Mayor Booker in particular looked like a very strong competitor. Post-Sandy, however, the political environment has changed, at least for now.”

The poll was conducted from Nov. 14 to Nov. 17 and has a margin of error of plus or minus 2.9 percentage points
